You will find that eating food without sauce and heavy seasonings will keep you on the fitness path. Have your protein with only a little salt and pepper or a dry seasoning. Try adding some dried Dill to your fish.
Chicken can get boring. Look in the seasoning aisle at your grocery store for these options to add flavor: Italian Seasoning, Garam Masala, Herbs de Provence or Greek Seasoning. These are low sodium options to give some spice and flavor.
Try to keep the salt to a minimum. If you need to add some you should only do a little while you are cooking instead of adding it when you sit down. Avoid premixed seasoning packets unless you read the label and it isn’t high in sodium.
